Abstract
A flow control system for controlling exhaust flow can measure effluent escaping from the exhaust hood at a given flow rate. An interferometric detector can measure fluctuations in fluid properties external to and/or in the vicinity of the exhaust hood. The flow control system may vary a flow rate of the exhaust hood and/or control exhaust hood structures responsive to the measurements to contain the effluent while minimizing the exhaust of air from the occupied space.
Claims7
An exhaust system, comprising:
- a programmable controller;
- an exhaust hood positioned over a cooking appliance;
- a video camera adapted for generating thermal images of a scene captured thereby, the video camera being connected to the controller and positioned and aimed to view the exhaust hood so as to capture images of a vicinity of the exhaust hood such that any thermal plume generated thereby;
- the controller being programmed to classify images generated by the video camera;
- the controller being connect to a fan and adapted to control an exhaust rate responsively to a result of a classification of said thermal images.
